Fun with Quadratics
I love teaching quadratics! Factoring, the Quadratic Formula, Projectile Motion... all of it is just awesome. It's the unit in Algebra 2 where I see the most student growth. It also seems to be the unit that makes my students the most proud of what they have learned to do.
Our quadratics unit starts with factoring and ends with projectile motion. In between, we learn the Quadratic Formula and begin getting comfortable with the graphing calculator. The Quadratic Formula always completely freaks my students out! To help, I print a stack of the above Quadratic Formula template that we then use for warm ups, quick checks and exit tickets. It helps their confidence a lot to get this extra practice.
Students love choice!
When I first started using choice in my classroom I didn't think it would really make much difference. It does! Students are so much more motivated and bought-in when they feel they have a say about the work they are doing. For the activity we use to summarize the Quadratic Formula, I give my students 12 strips of paper, each with a quadratic to solve. I was lazy and didn't cut them out ahead of time, but this actually worked out great. My students liked the hands-on aspect of getting scissors and cutting the strips. See? Sometimes laziness pays off.
No, I'm just kidding. It was a happy accident.
All of the equations were factorable but my students usually chose to use the Quadratic Formula. When a student completed a problem, I was able to quickly scan the QR code with my QR scanning app. NOTE: Snapchat scans QR codes!
Once an answer was correct, it was ready to be made into a chain link. I awarded 10 points for each correct link and extra credit points if anyone went beyond 10.
After learning the Quadratic Formula, we move onto solving with the graphing calculator. Because I love templates so much, we use one here too.
